Open platforms historically undergo a lot of scrutiny, but there are a lot of advantages to having an open source platform from a security standpoint.

"Einstein need not wait for an apple to fall"...That is the essence of Open Source Software..

Open source can propagate to fill all the nooks and crannies that people want it to fill.

For me, open source is a moral thing.

We're excited by the success of WhatsApp on top of Android. Amazon brings services like Kindle on top of Android. It's a competitive world and a lot more complex than people realize. When you run a platform on scale, you have to make sure it's truly open. That way, not only do you do well, so do others.

We're very opportunistic when it comes to open source.
